PDS state transitions
The internal state of the servo amplifier is managed by the PDS state defined in the CiA 402 drive profile specification. After
the PDO communication is established (after the AL state has reached "Operational"), the status is controlled by the master
station transmitting commands (by setting Controlword) in accordance with the following table. Once the state transitions from
"Not ready to switch on", which is right after turning on the power supply, to "Operation enabled", the servo motor becomes
ready to operate.
